Li Hong

Li Hong, formally Emperor Xiaojing with the temple name of Yizong (義宗), was a crown prince of the Chinese dynasty Tang Dynasty. He was the fifth son of Emperor Gaozong and the oldest son of his second wife Empress Wu, and he was made the crown prince in 656. As he grew older, he often came in conflict with his ambitious and powerful mother Empress Wu, and it is commonly believed by traditional historians that she poisoned him to death in 675. His father Emperor Gaozong, then still reigning, posthumously honored him with an imperial title.
